Attosecond (as). An attosecond is 10⁻¹⁸ of a second, the scale of electron motion in atoms.
Second (s). The second is the SI base unit of time, defined by the caesium-133 atom.
There are 1 × 10⁻¹⁸ seconds in one attosecond.
Multiply the number of attoseconds by 1 × 10⁻¹⁸. For example, 10 attoseconds equal 1 × 10⁻¹⁷ seconds.
One second equals 1 × 10¹⁸ attoseconds.
1 × 10⁻¹⁵ seconds. Other common values: 100 attoseconds = 1 × 10⁻¹⁶ seconds and 10,000 attoseconds = 1 × 10⁻¹⁴ seconds.
